【摘要】 本文制备了具有低反射率特性和光催化性能的三层复合薄膜SiCxOy/SnO2:F/TiO2。SiCxOy层直接沉积在玻璃基体上,作为障碍层避免离子从玻璃基板扩散到最外的功能层。而SnO2:F和TiO2作为功能层则分别使复合薄膜具有低反射率和光催化性能。利用X射线衍射(XRD)、扫描电子显微镜(SEM)和傅立叶变换红外光谱仪(FTIR)对样品进行表征。与纯TiO2薄膜相比,复合薄膜由于表面粗糙,以及TiO2到SnO2层界面间的电子移动,表现出较高的光催化性能和亲水性。另一方面,由于SnO2:F层的低E特性,复合薄膜的远红外反射率随着TiO2薄膜厚度逐渐增加而减少。更多还原

【Abstract】 A triple-layer composite film of SiC_xO_y/SnO₂:F/TiO₂,which combines low-emissivity（low-e） property and photocatalytic activity for the glasscoating,was fabricated.The layer of SiC_xO_y is deposited directly on glass substrate,acting as the barrier layer to prevent the ions diffusion from glass substrates to outside layers.The functional layers of SnO₂:F and TiO₂ devote to low-e and photocatalytic activity properties for the composite film,respectively. Measurements were performed by X-ray Diffraction（XRD）,Scanning Electron Microscopy（SEM） and Fourier Transform Infrared（FTIR） spectrophotometer.Compared to the pure TiO₂ film,the composite film shows higher photocatalytic and hydrophilic activities,which might be due to the rugged surface and the interfacial electron transfer from TiO₂ layer to SnO₂ layer.On the other hand,the reflectance of composite films in far-range infrared region,which is due to the low-E property of SnO₂:F layer,decreases with the increasing of TiO₂ film thickness.更多还原
